Geometry and dynamics of vortex sheets in 3 dimensions [PDF]
, 2002 We consider the properties and dynamics of vortex sheets from a geometrical, coordinate-free, perspective. Distribution-valued forms (de Rham currents) are used to represent the fluid velocity and vorticity due to the vortex sheets. The smooth velocities

Dynamics of vortex shedding from slender cones [PDF]
, 2009 PhDThe dynamics of vortex shedding from bluff bodies has been investigated experimentally for many decades, with the simple geometric case for the investigation being a uniform circular cylinder aligned with its axis normal to the flow. Even though

Intake Ground Vortex Aerodynamics [PDF]
, 2008 When an aircraft is operating in static or near static conditions during taxiing or take-o a vortex can form between the ground and the intake. With engine diameters increasing, intakes are moving non-dimensionally closer to the ground and as a ...

Forma, 2015 Summary: Dynamics of vortices of filament type is introduced for the following three cases: deformation of a vortex filament by self-induction, entanglement of two vortex filaments by self- and mutual inductions and reconnection of two vortex filaments. The first two cases are treated by the use of vorticity equation without the viscous term, while the

Wake structure and kinematics in the vortex ring state [PDF]
, 2009 High-resolution computational simulations of the vortical wake of a rotor operating both near to and within the vortex ring state have been conducted using Brown's vorticity transport model.

Universal dynamics in the expansion of vortex clusters in a dissipative two-dimensional superfluid
Physical Review Research, 2020 A large ensemble of quantum vortices in a superfluid may itself be treated as a novel kind of fluid that exhibits anomalous hydrodynamics. Here we consider the dynamics of vortex clusters under thermal friction and present an analytic solution that ...

How trapped particles interact with and sample superfluid vortex excitations
Physical Review Research, 2020 Particles have been used for more than a decade to visualize and study the dynamics of quantum vortices in superfluid helium. In this work we study how the dynamics of a collection of particles set inside a vortex reflects the motion of the vortex.

A highly adaptive three dimensional hybrid vortex method for inviscid flows and helically symmetric vortex equilibria [PDF]
, 2012 This thesis is concerned with three-dimensional vortex dynamics, in particular the modelling of vortex structures in an inviscid context. We are motivated by the open problem of regularity of the inviscid equations, i.e.

Parametric resonance in the dynamics of an elliptic vortex in a periodically strained environment [PDF]
Nonlinear Processes in Geophysics, 2017 The model of an elliptic vortex evolving in a periodically strained background flow is studied in order to establish the possible unbounded regimes.

Applications of point vortex equilibria: blocking events and the stability of the polar vortex [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2015 The present study investigates non-linear dynamics of atmospheric flow phenomena on different scales as interactions of vortices. Thereby, we apply the idealised, two-dimensional concept of point vortices considering two important issues in atmospheric ...
